Fall Protection
2
Falls in Construction
 Falls are the leading cause of deaths in the construction
industry.
 Most fatalities occur when employees fall from opensided floors and through floor openings.
 Falls from as little as 4 to 6 feet can cause serious losttime accidents and sometimes death.
 Open-sided floors and platforms 6 feet or more in height
must be guarded.
3
Fall Protection
This presentation will discuss:
 The working conditions that prompt use of fall protection
 Options that are available to protect workers from falls
At the end of this topic, you will be able to:
 List at least four methods of fall protection available for
protecting workers
 State the main criteria that prompts use of fall protection for
construction workers
Group Activity
Find the locations in the 1926 OSHA standards that require the use
of fall protection
4
Fall Protection Options
Guardrails
Personal Fall
Arrest System
(PFAS)
Safety Net
5
Fall Protection Planning
Lanyards and PFAS in use
Fall protection systems and work practices must be in place before you start work.
6
Personal Fall Arrest Systems
 You must be trained how to properly
use PFAS.
 PFAS = anchorage, lifeline and body
harness.
7
Safety Line Anchorages
Must be independent of
any platform anchorage
and capable of
supporting at least 5,000
lbs. per worker
8
Guardrails
Top Rail
Mid- Rail
Toeboard
 Top rails between 39 and 45 inches tall
 Toe boards at least 3 1/2 inches high
9
Safety Nets
Place as close as possible, but no more than 30 feet below where
employees work
10
When Fall Protection is Needed




Walkways & ramps
Open sides & edges
Holes
Concrete forms &
rebar
 Excavations




Roofs
Wall openings
Bricklaying
Residential
Construction
11
Walkways and Ramps
Guard ramps, runways, and other walkways
12
Fall Protection Residential Construction
In residential construction, you must be protected if you can fall more than 6 feet
13
Unprotected Sides & Edges
Unprotected edge
Unprotected sides and edges must have guardrails or equivalent
14
Sides & Edges - Improper Guarding
This 1/4" nylon rope alone is not a proper way to guard this open floor
15
Sky Lights and Other Openings


Holes more than 6 feet high must be protected
This opening could be made safe by using a guardrail, or strong cover
16
Floor Holes
Improperly
Covered


Cover completely and securely
If no cover, can guard with a guardrail
17
Concrete Forms and Rebar
 Use PFAS when working on formwork or rebar
 Cover or cap protruding rebar
18
Excavations
Guard excavations
more than 6 feet
deep when they are
not readily seen
because of plant
growth
or
other
visual barriers
In addition to needing
guarding, this excavation is
not properly shored
19
Roofs
If you work on roofs and can fall more than 6 feet, you must be protected
20
Wall Openings
Wall opening
If you work near wall openings 6 feet or more above lower levels you must be protected
from falling
21
Good Work Practices
 Perform work at ground level if possible
 Example: building prefab roofs on the ground and lifting into place
with a crane
 Tether or restrain workers so they can't reach the edge
 Designate and use safety monitors(This is less desirable of all
the systems)
 Use conventional fall protection
22
Training
Employers must provide fall protection training
The training is to teach you:
 How to recognize hazards
 How to minimize hazards
The training must cover:
 Fall hazards
 Fall protection systems
 Use of fall protection devices
23
Summary
 If you can fall more than 6 feet, you must be protected
 Use fall protection on:
 walkways & ramps, open sides & edges, holes,
concrete forms & rebar, excavations, roofs, wall
openings, bricklaying, residential construction
 Protective measures include guardrails, covers, safety
nets, and Personal Fall Arrest Systems
24
Is This a Fall Hazard?
Photos in this presentation are from the OSHA Region 4 National Photo Archive and OSHA Region 5.
25
YES
Workers could
fall while
climbing on the
shoring structure
to set it up and
remove it.
Ladders
and lifts
must be
provided.
26
Any Fall Hazard Here?
27
YES
Workers are exposed
to a fall hazard greater
than 6 feet, while
working near stairwell
opening.
Workers
must be
protected
from falls
over 6 feet.
28
Is This a Fall Hazard?
29
YES
Unprotected open-sided
floors 6 feet or more above
ground level.
Guardrail
systems,
safety net
systems or
personal fall
arrest systems
are required.
30
Any Fall Hazard Here?
31
YES
Workers are installing a
new metal roof without fall
protection.
NOTE: Remember that ladders must extend 3 feet above the landing area.
32
Is This a Fall Hazard?
33
YES
The photo shows
a mid-rail and
toeboard are
missing on an
open-sided floor
of a building.
This could
expose
workers to
a 12 foot
fall.
Toeboards are
required to
protect workers
below from
falling objects.
34
Can You Identify the Fall Hazard?
35
YES
Lack of fall
protection for
workers on
fabricated frame
scaffolds.
Planks appear to
be overloaded
and there is no
safe access for
workers.
The workers are
exposed to a 35foot fall hazard
from a scaffold
while stacking
blocks prior to
overhand
bricklaying
operations.
36
Can You Identify the Fall Hazard?
37
YES
Ladder to work
platform is not of
sufficient length.
It must
extend 3
feet above
the
working
surface.
38
Is This a Fall Hazard?
39
YES
Worker is
working off of the
top of a step
ladder.
The top of a
stepladder
shall not be
used as a
step.
40
Can You Identify the Fall Hazards?
41
YES
A worker is
working from a
carpenters'
scaffold that has
no guardrail,
extends too far
beyond either
end, and is not
wide enough.
The worker also does not
have proper access to the
scaffold.
The worker inside of
the window is not
provided with fall
protection as there is
no standard guardrail
for the window.
The worker working below is exposed to
the struck-by hazards of tools and
equipment falling from the employees
working above.
NOTE: A competent person must supervise as scaffolds are erected, moved and taken apart.
42
Any Fall Hazard Here?
43
YES
Workers working on
balcony of structure
exposed to fall
hazard due to
unprotected
side/edge.
44
Is This a Fall Hazard?
45
YES
Worker working on an
8:12 pitch roof with
only the lifeline tied to
his waist as fall
protection.
Employer
must
provide
full body
harnesses.
46
Is This a Fall Hazard?
47
YES
Scaffold was not
erected with guardrails
in areas where
workers were working
at heights greater than
10 feet.
